Figure 1 and 2 show the elephant seals production of offspring, female and male respectively. FIgure one which sepicts the female seal shows that they have a weak sexual selection. In figure 2 you can see that only a very little percentage of males produce a lot of offspring, and a little produce some and many produce very little to none. These two figures can show us how the elephant seals sexual selection depends entireley on males and rarely on females at all. The male elephant seal clearly has the strongest sexual selection. Their ability to reproduce is based solely off of size and strength that is put in competition with one another during fights for the area that contains many fertile females. Figures 3 and 4 are similar to figure 2 in that it shows a gap from offspring around 10-15 off spring to around 35-40 offspring. This is in both the vole figures and shows that not just one gender of the animal has all the strength in sexual selection but it is more base on each gender having better genes or being stronger or something, instead of elephant seals which have just the male fight over the females. In the vole species both genders compete for reproduction. This means that the best of the best from each gender mate with the best of the best and they produce a lot of offspring while the rest of the population does not produce or rarely does.
